Abstract: A system having a remote data center that broadcasts, to a various data centers, a cluster of software and a start instruction. The start instruction commands each of the various data centers to execute a master application when a processor in each of the various data centers extracts the master application from the cluster of software. The processor can extract an active pod and a standby pod from the cluster of software and determine whether or not an IP address conflict exists between the IP address of the active pod and the IP address of the standby pod.

Abstract: A system having a remote data center that broadcasts, to a various data centers, a verification application and a start instruction that commands each of the various data centers to execute the verification application.
